摘 要:

甘薯是起源于热带的粮食经济作物。甘薯贮藏过程中低温会诱导特定基因表达, 引起生理活动发生变化, 严重影响着甘薯品质。因此, 研究低温对甘薯贮藏的生理和分子调控机制以及甘薯耐冷性机制具有重要的理论和实践价值。本文根据国内外研究成果, 总结了在低温胁迫下甘薯贮藏过程中的营养及生理的变化过程, 并对可能的生理及分子调控机制进行综述, 进而为提高甘薯抗冷性并培育出优质品种的相关研究提供理论依据。

Abstract:

Sweetpotato is an economic food crop which originates from the tropics. During the storage period, the expression of specific genes and the change of physiological indexes induced by low temperature, which seriously affected the quality of sweetpotato. Therefore, Studies on the physiological and molecular mechanism during the storage period and the mechanism of cold resistance of sweetpotato have important theoretical and practical value. According to the research results at home and abroad, we expounded the change process of nutritional and physiological indexes and reviewed the probable physiological and molecular mechanisms of sweetpotato during storage under low temperature stress, which would provide theoretical basis for improving the cold resistance and cultivating high quality varieties of sweetpotato.

Key words: sweetpotato; low temperature stress; storage; research progress
